Enwere ike kewaa corrosion n'ime corrosion chemical na corrosion electrochemical

Wear design factor slurry pump manufacturer 's Many wear design factor slurry pump emeputa , na akụkụ dị iche iche na akụkụ dị iche iche nke eyi usoro abụghị otu , ma n'ozuzu nwere ike ichikota na atọ edemede:

1 Erosion : Na slurry mgbapụta emeputa n'oge arụ ọrụ, mmiri mmiri ka siri ike irighiri ebu na eruba ọnụego n'elu nke mmetụta so, butere ihe onwunwe ọnwụ. Dị ka nyocha nke ọdịda nke akụrụngwa wear elu ozize usoro nwere ike kewaa n'ime ịcha eyi na deformation yi na ike ọgwụgwụ eyi nke ọnwụ + mejupụtara deformation.

2 cavitation mebiri : N'oge arụ ọrụ nke mgbapụta ahụ, ihe ndị na-asọpụta nke mpaghara mpaghara (na-emekarị na ntinye impeller mgbe e mesịrị), n'ihi ihe ụfọdụ, mmiri mmiri na-agbanye n'ime oge mgbe nrụgide zuru oke na-adaba na nrụgide vapor nke okpomọkụ, na nke a mmiri mmiri na-amalite vaporized iji mepụta uzuoku , nhazi nke egosipụta . Afụ ndị a nwere mmiri mmiri na-aga n'ihu, ruo na nrụgide dị elu, afụ ndị ahụ na-ada n'ụzọ dị ịrịba ama belata ọbụna. Ka ọ dị ugbu a na condensation nke afụ, irighiri mmiri mmiri na-ejuputa oghere dị elu, ma nwee mmetụta siri ike na elu igwe. Nke a na metal elu spalling n'ihi mmetụta nke ike ọgwụgwụ , N'ihi na ihe onwunwe ọnwụ , oké metal elu na-egosi mmanụ aṅụ. Akụkụ nke cavitation na-emekarị na oghere impeller na ntinye volut.

3 na-emebi emebi: Mgbe usoro mgbasa ozi nwere ụfọdụ pH,emeputa mgbapụta slurryeruba mmiri ga-eme corrosive eyi, ya bụ ọnwụ nke ihe phenomena ime n'okpuru nkwonkwo edinam nke corrosion na eyi.

Enwere ike kewaa corrosion n'ime corrosion chemical na corrosion electrochemical. Chemical corrosion nke metal na mmiri mmiri media nzaghachi kpọmkwem na-ahapụ metal ọnwụ , electrochemical corrosion na mmiri mmiri na-ajụ bụ ọrụ nke metal elu na-etolite micro-batrị na-ahapụ ihe ọnwụ. Ebe ọ bụ na n'ezie ojiji nke metal ihe onwunwe bụ multiphase polycrystalline ihe, Ya mere, a bụ isi corrosion , electrochemical corrosion , karịsịa crystal ókè corrosion, intergranular cracks na-guzobere metal na-ebupụta , na ikewapụ ike frasi ọka ma ọ bụ , furu efu nkwado , n'ihi ya, ọ ga-apụ apụ. na mbuze mere irighiri ihe siri ike; mgbe scouring ndị siri ike ahụ, na metal elu corrosion n'ihi passivation oyi akwa na akwụkwọ ji agwụ na-emepụta mmiri mmiri ọkara na kọntaktị na metal elu-amụba ọhụrụ corrosion. Ndị na-emepụta mgbapụta slurry na nyocha ọdịda nke ịdị adị nke ihe ahụ achọpụtala na ọ nwere corrosion.
